I just turned in a ticket for mine. It's clicking now. They say don't leave oscillation on for more the. 18hrs a day. They asked me and I told them I didn't. If you do that might disqualify you for a replacement. But they sent a replacement immediately.
Also replacement for my Controller 69 pro as it randomly shuts off my lights. It may last 10 seconds or 30 and randomly comes back on. They try ticking you on if you switch lights will it work or blah blah. But it flat-out turns my lights off so I needed a replacement and they did.
I should be receiving both this week.
The clicking noise is from leaving oscillation on for more then 18hrs a day tho. Instead of leaving it on constantly turn it to a schedule. I do 10 minutes on then 5 off. This should help.
Please select me as the answer so I can be entered for a chance to win grower of the month contest I would really appreciate it if you did growmie. Goodluck on replacements I had no issues getting them to cover it in warranty.
